IMPROVEMENT IN RAKINGDEVYICDES FOR HARVESTERS.

Specification forming part of Letters Patent No. 41,080, dated Janu'aryh, 1864.

To all whom it may concern.-

Be it known that we, G. W.- MARSH and ,W. W. MARSH, of Shabbona, in the county of De Kalb and State of Illinois, have invented a new and Improved Raking Device for Harvesters; and we do hereby declare that the following is a full, clear, and exact description of the same, relerence being had to the accompanyin g drawi n gs, niakiu g a part of this specification, in which- Figure l is a front view of'the frame of a harvester having our invention applied to it; Fig. 2, a plan or top view of the same.

Siinilar' letters of'refereuce indicate .correspending parts, in the two figures;

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a horizontal rectangular frame, in which a horizontal band, B, is placed, and fitted over rollers a a, This .band B extends the whole width of the frame A, and moves in the direction indicated by the arrow 1.

(3 represents the sickle, which may be of the ordinary reciprocating kind, and works at the front of the frame A. This sickle has a series of upright ribs or projections, b, attached to its back part, the upper edges of said ribs or projections being inclined, so as to leave a vertical face, 0, atone end, as shown clearlyin Fig. 1, the upper edges of the I'ibS extending at one end down to the sickle G.

D represents an endless toothed apron, orrit may be termed an endless band of rakes. This toothed apron has an inclined position, and it works over rollers d d, one'of which, d, has its hearings in the' frame A,and the other, (1 its hearings in an upright frame, E, attached to the frame A. The toothed apron D moves in the direction indicated by the arrow 2, and the apron I) and band Bare moved'by power applied to the upper roller, a, of the apron D, motion being communicated from the roller d to one of the rollers a of the apron by a belt, 0. The pulleys ff, over which the belt 6 passes, are of difl'erent diameters, the pulley f of the roller d being of larger diameter than the pulley f of the roller a. Hence it will be seen thatthe bandB willmove quicker than the toothed apron D.

F is a belt, which passes around pulleys g g at the ends of the rollers d a, which are opposite to the ends on which the pulleys f f are placed. This belt F is'pro'vided with teeth It at suitable and equal distances apart.

Theoperation is as follows: As the harvester is drawn along the grain is cut by the sickle( and falls upon the band B the butts of course being at the front part of the band B. The

' band B,by its movement,-conveys the cut grain -to the toothed apron D; but the grain will not fall evenly, so that the straws will be perfectlyQparallel with each other on the band B. -It witl fall more or less obliquely, accord? ing to the position in which it may stand when cut. The grain or straw is brought at right angles with the band B'by twodifl'erent means, one being the ribs or projections b, which, as the .sickle 0 moves in the direction indicted by arrow 1, catch the straw and shove it for,- ward in the direction theband B is moving, and, during the return movementol' the sickle, slip under the straw and. catch it again at their vertical faces or -sides 0, when the movement of the sickle changes; The other'meansfor straightening the grain or bringing the straw parallel consists in the dili'erence of speed be tween the band B and the toothed apron D In consequence of the former having rather a straws all parallel with the latter, and the grain consequently can be taken from the box or receptacle into which it is discharged-from D in an even state, so that it may bebound with facility. I

' G G are the binders tables, secured to the frame A.

Thereceptacle into which the grain .is discharged (not represented) may be just belowthe upper part of the toothed apron l).

Having thus described our invention, whatv the toothed apron D and endless band B, as we claim as new, and desire to secure by Letand for the purpose set forth. tei's Patent, is-

1. Providing the sickle G. with ribs or projeetiolns b when the latter are used in eombination with the endless band B and toothed Witnesses: apron D, for the purpose specified. SAMUEL MARSH,
